Background:
- Current upper-limb prostheses control methods have limitations, particularly with myoelectric signals for complex movements.
- Improvements in amputee training, prosthesis dynamics, and control signal quality are crucial for better prosthetic function.
Purpose of the Study:
- To discuss necessary improvements in upper-limb prostheses control.
- To explore the potential of neuroelectric signals as a superior alternative to myoelectric signals for prosthetic control.
Main Methods:
- Discussion of control strategies for upper-limb prostheses.
- Evaluation of myoelectric signal limitations for multi-degree-of-freedom prostheses.
- Presentation of experimental results for implantable electrodes detecting neuroelectric signals.
Main Results:
- Substantial improvements in prostheses control are possible via amputee training, improved dynamics, and enhanced forward-path control signals.
